1. Benthic diatoms in the Gulf of Bothnia : Community analysis and diversity
Sammanfattning : Benthic diatoms are valuable tools for biological monitoring and paleo-ecological reconstruction of past environmental conditions. This thesis aims at describing size-related properties of benthic diatoms and suggests that data assessment for community analysis can be improved by considering the importance of scale. LÄS MER
2. Modelling spatial and temporal species distribution in the Baltic Sea phytobenthic zone
Sammanfattning : Statistical modelling is often used to relate the presence or abundance of species to environmental predictors, thereby providing a basis for predictive mapping of species or biodiversity. The variables included must thus be relevant and reflect actual changes in the environment. LÄS MER
3. Phytobenthic communities in the Baltic Sea - seasonal patterns in settlement and succession
Sammanfattning : Seasonal changes in reproduction, recruitment, occurrence and growth of marine plant and animal species is a common phenomenon world-wide. This thesis investigates whether such seasonal changes could determine the succession in subtidal phytobenthic communities on free space in the Baltic Sea. LÄS MER
